guaiacol usage and synthesis |
chemical properties | light yellow oil |
usage | expectorant |
definition | chebi: a monomethoxybenzene that consists of phenol with a methoxy substituent at the ortho position. |
general description | colorless to amber crystals or liquid. density (of solid) 1.129 g / cm3. solidifies at 28°c (82.4°f), but may remain liquid for a long time even at a much lower temperature. slightly water soluble . soluble in aqueous sodium hydroxide. used medicinally as an expectorant. used, because of its anti-oxidant properties, as an anti-skinning agent for paints. |
air & water reactions | sensitive to air and light (darkens). slightly water soluble. |
reactivity profile | guaiacol may react with oxidizing materials. guaiacol forms salts readily with bases. |
fire hazard | guaiacol is combustible. |
